目前已建立了一些动物模型用于检测外科手术术后的病理生理后果,但是这些模型中的麻醉方法、监测和管理措施与用于人类的大有不同。本研究旨在建立一个使用与临床相似的麻醉方法和围手术期治疗的腹部手术大鼠模型,并探究不同损伤程度和麻醉镇痛深度对手术应激及术后恢复的影响。

异丙酚静脉麻醉下进行腹部皮肤/肌肉切开并与剖腹探查术对比,并结合吸氧、补液、保暖、血气分析、预防感染等围术期措施。监测麻醉和手术期的应激指数(平均动脉压,心率,血糖,以及血浆皮质酮),术后评估恢复指标(体重,食物消耗和疼痛)。此外,接受剖腹手术的动物接受低和高剂量的丙泊酚和舒芬太尼,以检查麻醉和镇痛的深度和恢复期应激之间的关系。

结果发现,与躯体损伤相比,剖腹探查引起了更大的应激反应,造成术后恢复较慢。大剂量舒芬太尼比大剂量丙泊酚能更有效地降低血浆皮质酮的水平,并改善术后恢复(P<0.05)。总体而言,本研究成功建立了一个使用与临床类似麻醉方法和围手术期治疗的腹腔手术的大鼠模型。模型研究结果显示,手术创伤的严重程度与应激反应及术后的恢复呈正相关,适当镇痛在减轻手术应激和改善术后恢复方面有明显的作用。
